State Sen. Tim Solobay (D-Washington) wants the commonwealth to become the 21st state to prohibit the sale of electronic cigarettes to minors.

E-cigarettes have been marketed as a healthier alternative to regular cigarettes, but a study from the Centers for Disease Control and Prevention suggests they could be a gateway to regular cigarette use.

The study showed 160,000 teens nationwide who never smoked cigarettes before used electronic cigarettes in 2012.

The devices are battery-powered and provide users with doses of nicotine and other additives in an aerosol.
